Connecting An Antenna To The Reader - Siemens Simatic Rf642A Betriebsanleitung

Connecting an antenna to the reader

The SIMATIC RF642A antenna must be connected to the reader using an antenna cable.
Preassembled standard cables (Page 2) in lengths of 3 m, 10 m, and 20 m are available for the connection.
The range of the antenna is limited by the cable loss. The maximum range can be achieved with the cable 6GT2815-0BH30
(length 3 m), since this has the lowest cable loss.
Requirement
Note
Use of Siemens antenna cable
